maiil log file analysis by sender uid
« on: February 10, 2004, 05:37:06 PM »
I was going through our mail log files since it seemed that mail was slowing down as of late due to lots of MyDoom stuff.

I did a Mail Log File Analysis/ Sender UID, and came up with the following:

 mess      bytes     sbytes     rbytes  recips  tries         xdelay  uid
    2       3384       3384       3384       2      2       0.044649  0
 6862   99774675   99774675   99774675    6862   6862     521.739998  101
26256  451113373  313697711  451119838   26259  26259   67865.121550  400
11136  238809335  257685598  259649684   12910  12915    2163.614738  401
14387  219913744  146441297  219913744   14387  16438  662901.648382  406

(Sorry if this table is screwed up- couldn't figure out how to format it)  

What is relevent is that 6800+ messages from uid 101, 26,000+ messages from uid 400,11,000+ messages from uid 401 and 14,000+ messages from uid 406.  It seems that "real" users, have mail tagged with both the 400 and 401 UID's; UID 406 only shows "<#@[]>" and "<>" as the sender.

What do these uid's attach to, and how concerned should I be that this much e-mail is going out?  I only have about 20 users and we CAN'T be sending this much mail!

Thanks,
Neil
